Question

Difference between uniform linear motion and uniform circular motion

Answer 1

Uniform motion in general is used to indicate that the object is covering equal distances in equal intervals of time, ( not necessarily moving with constant VELOCITY but rather with constant speed). In uniform linear motion, the acceleration of the body is zero as it has constant speed and moves in a straight line whereas in uniform circular motion, although the object has constant speed, it's velocity keeps changing, I. e., the direction of speed changes every moment and since velocity is a vector quantity, it changes too. So, in linear motion there is no acceleration but in circular motion, there is an acceleration( to change direction of velocity).
